Also suggest that Firebeard and Tethoril are partners in crime. I mean, Firebeard? The dirty arsonist left a clear clue in his name!

In fact the evidence clearly points to Firebeard as the arsonist, and Tethoril blackmailing him. Both crimes. Tethoril has even tried to get us involved in his blackmail by trying to get us to deliver the blackmail note (cunningly disguised as a 'scroll of identify').

This is truly beautiful. I love it. Definitely needs to finish up with Imoen and unceremoniously rifle through his dead foster father's personal effects to grab some loot, and potentially a replacement glasses of +2 coolness. That iron crisis has fried your last pair all to hell.
